Glossary 17-hydroxyprogesterone

steroid hormone involved in cortisol and sex hormone production

17-hydroxyprogesterone (17-OHP) is a steroid hormone produced in the adrenal glands and gonads as part of the process of synthesizing cortisol and other hormones. Elevated levels of 17-OHP can indicate congenital adrenal hyperplasia (CAH), a genetic disorder affecting hormone production, and it is often measured in newborn screening tests to diagnose this condition early.
